LDDRIGATING SYSTEM.

To all whom it may con-cern:

' *Be it known that I, ALFRED WARD, a citizen of the United States, residing at Queens St., St. Albans, Long Island,fin the county of Queens andState of New York, have invented certain new and useful Improvements-in Lubricating Systems; and I do declare the following to be a full, clear and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved lu. bricating system for use inconnection withV an internal combustion engine and one object of the invention is to provide an i'mproved construction of reservoir tank by means of which warm oilv may be passed "reservoir, i ,l y y f Another object ofy the invention is to s`o construct this lubricating system that it isf," only necessary to provide the reservoir tank" through the reservoir tank into the pipe leading tothe circulating pump. y I

Another object of the invention is to so construct this improved lubricating system that warm oil maybe caused to pass throu h a conductor pipe in the reservoir and fed 'f `rectly to a straining screen at the upper end of the Ipipe leading to the circulating pump thus permitting a circulation o'f warm oil while the oil which has thickened in the reservoir tank is becoming l heated and thinned. a

Another object of this invention is to so construct this lubricating system that the oil from the crank case sump pump may be caused to flow either throu h the conductor pipe leading to the strainer .or may be caused to flow through a pipe having communication with theinterior of the reservoir and thus the oil permitted to b e deposited` either directly into the strainer or into the l fwith the motor running and the motor is svshut'oi for the night the oil will cool and Wit an improved construction in order permit a conventional construction of lubricating System to be easily converted into the improved construction.

This inventlon is illustrated in the ac-` companying drawingsrwherein': r

which lubricating oil will be poured through an inlet 2 closed by a removable cap 3. This reservolr is provlded with an outlet opening 4 and a ske eton frame 5 is secured to the bottom of the reservoir beneath and about theopening 4 and carries a cup 6 which is formed of screening and forms a strainer for the oil which passes through the outlet 4 of i the reservoir. A cup 7 is connected with the flange 8 of the skeleton frame 5 by bolts or other removable fasteners 9 and is provided with an outlet 10 through which oil will pass into the neck of the pipe 1l which leads to the circulating pump. This pipe is provided with a valve 12 bymeafns of which the flowof o1l from the cup 7 may be shut ofi' when desired and is further provided with aV p lug 13 which maybe lremoved when it is deslred to drain the pipe 11 with the valve 12 closedr The oil after it has been pumped to the va'rlous bearings of the motor through suit- 'able conductor pipes passes down into the 'Msystem of the usual t e the pipe 14 is connected with a 'pipe w ich extends up into `the reservoir 1 to a pointlabove the. oil level andthe oil is therefore emptied directly inta the reservoir.-` After the oil has been in use on a coldanight will thicken. Therefore when the motor is again started the bearings will not' be properly/lubricated as the oil @which has thickenedA will not flow properly.

r oil from the pipe 14selectivelyintofthey pipes-21 and 22 according to the position' ofk f 15'f'the valve 23.y This stem 28 is provided at from which extend pipes 21l and 22. The shell valve 23 which is rotatably mountedin the housing 16 is provided With outlet openings 24 andr 25 for registering respectively Withthe outlets 19 and 20 andy this valve is provided with a slot 26 through which ex tends a piny 27,to limit rotary movement of the reservoir and will permit passage of the itsupper end with a crosshead 30 which has I 'one end engaged by an actuating rod 31 and at its second end 1s p rovidedvvith 'a pin 32 engaged by :a spring 38. This spring 3,3 engages a pin 34: carried by the4 reservoir and will. serve toy normally retain they yvalve in the position" shown for directing the. oil

from they pipe 14; into the pipe 21 and through 'this pipe' intoy the reservoini f After the motorl has been idle for some.- ytime and the oil in the reservoir has become thickened; it. is desired kto feed Warm oil into f the outlet, a cupinclosing the outlet and the pipe 11 and in order to do so there has been provided a pipe 35 which extends yvertically in the reservoir-from the cup 36 through eyes 37 carried by the pipe 22 and down through'the strainer i6 into 'the lowerr portion ofthe cup 7 above :the outlet 10. f f' thereof. The Warm oil can thus be forced from a grease gun through the pipe 35 into the pipe 11 and will flow from this pipe to the circulating pump .which will force it through the lubricating system. This Warm oil will pass through the pipe 14 and with .the two-way valve turned to bring vthe port 25 into registry with the pipe 22 the oil lWill flow through this pipe 22 and back into the strainer: The Warm oil WillV tend to heat the thick oil-in the strainer and cup' as it ows through the strainer land back into the pipe 11 and the passage of the oil through the pipe `22 will heat this pipe and the oil in the reservoir will be gradually heated. After the oil in the reservoir has been heated to a sufficient extent the valve may be turned to the position shown in F-ig.

1 and-the oil Will flow through the pipe 21 back into the reservoir instead of passing through the pipe 22.` When the motor iS shut off for the night the valve 12 Will be closed and the plugs 13 and 18 removed.

The oil which drains out when these plugsare removed Willbe caught in a thermos bottle or other receptacle in which it can be kept Warm and this Warm oil will be put away until the motor is again to be used at which time it Will be poured into the grease gun and forced into the pipe 85 as previously stated. It will thus be seen that there has been provided an 'improved 'Wa-rm, cil maybe led through the reservoir lseen that there has-been provided a system yso constructed that a conventional construction of lubricating system maybe L easilyy l. An oil reservoir havingan inlet yand set position.
